Question

How many electrons are there in $p$-orbitals of silicon?

• A. 4
• B. 5
• C. 6
• D. 8

Answer 1

The correct option is D 8

In the periodic table of elements, silicon is represented by the chemical symbol $Si$, atomic number 14 and relative atomic mass of 28.085. It contains 14 protons and 14 electrons, with its most abundant isotope containing 14 neutrons.

Silicon contains 14 electrons that are distributed among five energy levels. The orbitals $1s2s,2p$ and $3s$ are filled first with 2, 2, 6 and 2 electrons, respectively. The remaining two electrons are placed in the 3p orbital. So, a total of 8 electrons are there in the $p$ orbital.
